IMPROVEMENT IN HORSE-RAKES.

Specification forming part of Letters Patent No. 26,293, dated November29, 1859.

. ing to be a full 'and exact description of the same, reference beinghad to the accompanying` drawings, making part ot this specification.

In the accompanying drawings, .Figure l is a plan ot' a horse-rakeembodying my improvement. Fig. 2 is a side view of the same with onewheel removed.

c is an axle revolving with the groundwheels, and carrying upon it acog-wheel, b.

c is a vertical rack adapted (in manner hereinafter explained) to bethrown in or out of gear with the cogwheel b. The said rack is ,at itsupper end pivoted to a frame, d, which frame is pivoted at c tostandards rising` from the main frame h of theimplement. f are theteeth, attached to the implement in customary manner to admit of beingraised at the proper moment to discharge.

G isa guard or bar provided with mortises through which the teeth pass.lThe said bar is attached tdthe fra-me d, so as to be raised or depressedtherewith, and'works at each end on a small standard, g, risingrfrom themain frame h, to guide it in a proper path.`

I is a lever provided with a friction-pulley, '12, and employed to pressthe rack c against the cog-Wheel b.

j is a second lever, which, when depressed, exerts an upward pressure onthe forward end of the frame d in order to keep the teeth firmly down totheir work. k are clearers of customary construction.

In order to discharge the teeth,it is only necessary to withdraw thefoot from the lever j and pla'ce it upon the lever I. This action,bringing the rack c into gear with the wheel 71, causes the said rack tobe drawn downward by the motion ofthe machine, thereby elevating theteeth through the agency of the frame d'and bar G.

The levers I andj may be adapted to be operated by either the foot orhand.

By this invention the driver is relieved from the labor of elevating theteeth by hand, and at the same time the draft of the animal isequalized. l claim as new and of my invention herein, and desire tosecureby Letters Patent- The arrangement ofthe cog-wheel b, rack c,lever I, frame d, bar Gr, standard g, and teeth f, operatingsubstantially as and for the purpose set forth.
